Grove of Dreams

The Grove of Dreams is a place where players may encounter Mythical Pokémon Jirachi. It connects to Route 9, and has 3 big trees -- a regular tree, a water tree and a fire tree, housing 3 Pokémon that are known as the "Elemental Monkeys".

Catching Jirachi
Underneath the rock wall behind the regular tree, there is a secret tunnel covered by some vines. Players can walk through which leads to the fabled ancient ruins explorers in the area have been looking for. If players walk up to the shrine overnight, stand in the middle and say "I wish for (Anything)", a cutscene will happen and a battle will be initiated with a Lv.25 Jirachi. Players only have 1 chance to catch it, so save beforehand and turn off the auto save function.

Catching Elemental Monkeys
Before entering Grove of Dreams, put a Fire-type, Water-type or Grass-type Pokémon in the first slot of party. The corresponding Elemental Monkeys may appear under their respective huge trees, click on those Pokémon to start the battle. If the Pokémon did not appear, exit to Route 9 and enter again.
